For me to use this graphic with a client, I would need a laymen’s description of how/why this is a safety device.
“GFCIs are designed to sense any difference in current between the supply on the ungrounded (hot) conductor in a circuit and the grounded (neutral) conductor.” . . . such as when you are shocked (new current path through you to ground). Typical time to trip is within a tenth of a second. Suitable to replace outlets where no ground conductor is provided.

You should remove the word any. GFCI’s do allow a small of current imbalance between the ungrounded conductor and the neutral. Typical Class A GFCI devices have a trip rating of 4-6 ma of current.
